Difference Between Mammals And Reptiles

There are many functional differences between the reptiles and mammals. First of all mammals are warm-blooded animals. The body temperature of mammals is regulated and kept consistent by the coating of hairs. On the other hand, the reptiles are cold-blooded animals, i.e. their temperature is influenced by the environment and do not have hair, but scales. In mammals embryonic development occurs inside the mother and the young are born. They are fed with milk secreted by mammary glands of the mother, while the reptiles lay their eggs inside which completion of embryonic development occurs. Another difference is that mammals have three bones in the ear (the hammer, anvil and stirrup), while in reptiles there is a single bone.

The mammals are a class of vertebrates. There are various differences among them. However, they colonize virtually in any environment of our planet from deserts to polar ice caps. Some of the mamal have evolved the fins or wings. Some of the mammals are able to colonize the aquatic environment and others are able to fly. A feature of mammals is the homoeothermy, that is, they are able to control and maintain their body temperature regardless of the environment. The mammals are provided with numerous glands such as sebaceous, sweat, mammary, and odoriferous. The body of almost all mammal species is covered with hair. The jaw of mammals consists of a single bone with teeth which are changed in the course of their lives.

The reptiles are a class of vertebrates. Their body temperature is influenced by the external environment. They do not possess mechanisms of internal adjustment as mammals and birds do. So, they are found in all parts of the world with the exception of colder areas of the planet. The reptiles represent the first group of vertebrates that have adapted to a strictly terrestrial environment and that have colonized the land. Their appearance on the earth varies greatly depending on the species. The body of the mammals may be round (turtles) Or flattened (alligators), elongated or worm-like, complete with legs or completely limbless (snakes). The skin of reptiles is very poor in glands and is usually provided with a horny ends. The jaw consists of three small bones on both sides and is provided with teeth which are more or less identical. Most reptiles are oviparous, that is, militate eggs, within which the embryo completes its development (with some exceptions).
